The sighting over the years of Large Black Cats and possible Thylacine is what attracted me to this sight many years ago.
I have had several experiences with Large Black Cats.
The first was in 1992 approx 50 km west of Esperance, we were fishing on a remote beach. A group of fellow fishers were approx 2kms further West of us. In the morning the other group packed up and passed us. Just after they left my mate pointed out a large black object moving around on the beach where the other group had been. Through Binos we watched what appeared to us to be a large cat searching for leftover scraps. We drove down to investigate and the creature ran off into the dunes behind. On arrival to the area there were prints approx the size of a clenched fist leading off to the dunes.
My second experience was ona chicken farm near Pinjarra. My neighbour at the time used to shoot foxes for a few extra dollars. On this night I went along. We inspected the fenceline to the chicken sheds and blocked all entry points except one. This is where the rifles were sighted. During the evening 5 foxes came to their demise. About midnight we were getting ready to go when there was a commotion in the shed. suddenly a black shape squeezed out of the tin siding with a chicken in its mouth. It soon became apparent it was alarge cat. We put the spottie on it as it scaled the fence. It was heavy build and approx 3-4ft long. I said shoot it! shoot it! but my offsider was just gobsmacked and stood next to me staring. The sighting was only a few seconds and it disappeared.
My next tale is of 2 possibel Thylacine sightings both in the same vicinity between Augusta and Margaret River WA. We had been hiking in amongst the Karri Forest collecting native seeds for a consrvation project in about 1983. When we got back to camp the two ladies who stayed behind were very excited. They claimed that after we had left a strange creature walked into the clearing and appeared to be awakening. They said when it yawned they knew it was a Tasmanian Tiger due to the jaw spread. The creature just stared at them and wandered off into the bush.
The second tale involves my now wife. We were camping in the same area. I had gone ahead with the dogs towards the beach. My wife was coming up behind after the call of nature. She says that as we went around the bend and out of view an animal appeared from the bush and stared inquisitively after us. She said it was striped, about the size of a medium dog. But what made her know it was not adog was its funny shape and it sort of hopped into the other sdide of the track like a roo. This was approx 20 years ago. I had not told her of the previous sighting in the same area and she is still convinced of what she saw.

Interesting sightings Believer, thanks for posting them.
Mat, if my memory is correct (my brain does get scrambled sometimes) there has been thylacine remains found on the nullabor. One in particular was in such a good state of preservation it was initially thought to be recent, but it turned out to be ancient. The good state of preservation was due to the hot dry climate and sheltered area it was found in.
Enough reason to think "just maybe"

Geez Shaz, I thought I'd trolled around the web sussing out all the crypto stuff, but I hadn't seen that angelfire addressed site. Just had a quick look at it. Guess what I'll be wasting some time reading through today.
Heres a thylacine story I bet noone out theres heard before. My ex mother-in-law (now deceased) went to school with the daughter of one of the keepers at Beaumauris Zoo and she always said that her friend told her the last tiger didn't die like the story goes, but was in poor health and one of the keepers shot it. Fact or not? I don't know.

Everybody knows tthat Thylacines existed from one end of Oz to the other, we have aboriginal rock art depicting thylacines up here in Arhnem land, the Barkly tablelands and the Kimberely, whos to say they do not exists in remote parts of WA, it is a pretty brave statement to say they cannot possibly still remain alive in these parts

As Topender said, it'd be a bold thing to suggest that they couldn't still be here. We overestimate our knowledge of the Australian wilderness all the time (which is what this site is predicated on, I suppose).

I've got no doubt that there are all sorts of things potentially wandering around in areas where hardly anyone ever ventures. 21st Century society assumes more often than it actually investigates; to our own detriment.

Lived in the sw of wa for 47 years and was always fascinated by the thylacine . Personally have never seen one . Hard to believe that they are still sighted in the area but I do know people who have .
In the 1930s they were quiet common around the busselton area . They were still around in some numbers in the 1980s . Sightings are rare nowadays.
Check out the pic on the net of Kevin Cameron's thylacine . This was in busselton in the 1980 s . It may be dead but it is still a real thylacine .
In the 1990 s I saw on numerous occasions a black leopard ??? Near Augusta . Once at 3 pm in the middle of a gravel road only meters away from me . I estimated its size as a conservative 60 kg at the time. I now have a dog that weighs 50 kg and looking back I'm guessing that cat would have been closer to 100 kg . I saw it at the same place on a semi regular basis for about 5 years .
There were other accounts in around the district at the same time. A mates grandfather even shot it with a shotgun . It leapt away .
In the last 20 odd years the sightings have diminished to nill .

Only last year though some shooters saw a large black cat in there scope . We're hesitant / shocked to shoot it . Finally at long range they fired and hit it . When they went to inspect it had gone . Both were a bit confused . A black cat in the Aussie bush that survives a hit from a high power rifle.
